It is called inlet spillage drag, a term used in the aircraft industry to describe the change in inlet drag with engine airflow. <> endobj endobj <> While these two components can increase cornering speeds when installed on your car, they will also increase drag and limit your top speed. Certain aspects of Aeronautical and Building Aerodynamics research are shown to be applicable to the study of the flow around road vehicles.
